This Christmas, there were a lot of     2    computers under the tree.     3    that computers are the key to success, parents insist that children     4    taught to use them in school as early as possible.
    The problem for schools is that when it     5    computers, parents do not always know best and are eagerly urging the schools to offer computer courses as soon as possible. Many schools are     6    parental impatience and are purchasing hardware hastily     7    good educational planning, saying "OK, we've moved into the computer age." Teachers     8    themselves caught in the middle of the problem between parental pressure and     9    educational decisions.
    Educators do not even agree     10    how computers should be used. A lot of money is going for computerized educational materials     11    can be taught     12    with pencil and paper. Even those who believe that all children should     13    to computer warn that there are potential     14    to the very young.
